I'm baffled. I just got 2 pairs of GORGEOUS flats that I love - one Dior, one CL. Both are pretty comfortable straight out of the box, but for some reason, whenever I step into them as I'm walking, they make a farting noise! I know it's air being compressed or something to that effect......but what the hell! What's causing that? Do you guys have experience with this? I want to keep these 2 flats because they're really perfect...but I can't look chic while *farting* all the time! ush: Any ideas for solutions..?
